kristallnacht

Casey Morell / Global Journalist

The 9th of November is an important day in German history, for both highs and lows. It's the day the Berlin Wall fell in 1989, and it's the day the German states became a republic in 1918 before the end of World War I.

However, November 9 is also the anniversary of Kristallnacht –  the night of broken glass. On that night in 1938, the Nazis led riots through the cities of Germany. Jewish owned businesses were ransacked; their storefronts defaced with graffiti; their windows smashed. Nearly 30,000 Jews were arrested that night alone, and sent to concentration camps throughout the Reich. Historians widely consider Kristallnacht to be one of the first major events in the run-up to the Holocaust.
